Description
This invention relates to a container or package and is
particularly concerned with a multicompartment package which can
readily be broken apart to form smaller containers or to remove
articles from the container.
Many articles are sold in units of one or in groups, depending upon
the purchaser's desires or needs, and when such articles are
supplied in multiple package form certain problems are introduced
because of the variation in the quantity sold. A particular item of
this nature, and in connection with which the present invention is
illustrated, is a disposable cutting insert adapted for being
detachably mounted on a tool holder. Such inserts are
advantageously packaged in groups of, say 10 but may be sold in
units of five, or even smaller units, and after having been sold
are usually dispensed for use one at a time.
It is a convenience and an economy for the manufacturer to be able
to package such inserts in groups of 10 and it is a matter of
considerable convenience to the purchaser to be able to dispense
the inserts from the package singly while the remaining ones of the
inserts remain in the package or container and are protected
thereby.
The present invention is particularly concerned with a novel
container or package arrangement especially adapted for packaging
articles, such as throwaway cutting tool inserts, so that a
convenience and economy results for the manufacturer, for sales
people, and also for the purchaser and consumer.
The present invention is also concerned with a container of the
nature referred to which protects articles placed there from damage
at all times.
Still further, the container according to the present invention is
constructed so that it can receive articles of different sizes and
all of which are retained within the container without excessive
freedom of movement.
FIG. 1 is a plan view looking down on top of a container according
to the present invention;
FIG. 2. is a bottom plan view looking up at the bottom of the
container;
FIG. 3 is a side view looking in the direction of the arrow III in
FIG. 1;
FIG. 4 is a transverse sectional view indicated by line IV-IV on
FIG. 1;
FIG. 5 is a longitudinal sectional view indicated by line V-V on
FIG. 1;
FIG. 6 is a perspective view showing a blister employed with the
container to retain articles therein;
FIG. 7 is a transverse sectional view similar to FIG. 4 but showing
a modification for locking the blister in the container;
FIG. 8 is a plan view showing a blister of a type different from
that of FIG. 6; and
FIG. 9 is a plan view of still another type of blister. SUMMARY OF
THE INVENTION
The present invention is concerned with a container, preferably of
plastic, such as, polystyrene, and having multiple compartments
therein arranged in two rows on opposite sides of the center of the
container. The container is formed with a weakened region extending
along the center so that it can be broken in two to provide two
smaller containers when a purchaser uses a smaller amount that is
contained within the complete container.
The container is also provided with weakened regions between
adjacent ones of the compartment on each side of the center of the
container so that the individual compartments can be broken off one
at a time to permit dispensing of the articles one at a time.
The compartments are adapted to receive the articles to be packaged
and the articles are confined within the compartments by blister
members which are retained in the compartments when they are
pressed therein.
To accommodate the container to articles of different size and
shape, blisters of different sizes and shape are provided, all
having the same dimensions overall so that all will fit uniformly
sized compartments of the container.
DETAILED DESCRIPTION
Referring to the drawings somewhat more in detail, FIG. 1--5 show a
container having a main body part generally indicated at 10 and
which is formed with a plurality of compartments 12, all of the
same size and shape. The compartments are defined by a bottom wall
14 of the body, a peripheral wall 16, a central longitudinal wall
18 and lateral walls 20 extending between the central wall 18 and
the peripheral wall 16 at the sides of the container.
At the ends of the container body, the lateral walls 20 are spaced
inwardly from the ends of the container body 29 to leave end
portions 22 and 24 which permit ready handling of the container and
which may receive identifying ledgends, or the like. Each
compartment 12 has a hole 26 provided in the bottom wall thereof in
about the center. This hole can be availed of for pushing the
articles therein out of the compartment. or for pushing the blister
out of the compartment so that the article will readily drop
therefrom.
As will be seen in FIG. 4, central wall 18 is in the form of an
inverted U-shape section so that between the row of compartments 12
on one side of the longitudinal center of the container and the row
of compartments 12 on one side of the longitudinal center of the
container and the row of compartments 12 on the other side thereof,
there is a weak region, designated by arrow 28, such that the two
side parts of the container can be broken apart quite readily. As
will be seen in FIG. 2 the end portions 22 and 24 of the container
are hollow toward the bottom of the container and the outer
confining wall portions thereof are interrupted at 30 so as to
provide a continuation of the weak region 28 completely to the ends
of the container.
Furthermore, as will be seen in FIG. 5, between each adjacent pair
of compartments 12, there is a second weakened region, indicated by
arrow 32, and formed by transversely extending slots 34 extending
through the bottom wall 14 of the container adjacent the pertaining
wall 20, and further more extending completely across the container
in the lateral direction. The slots 34 permit the individual
compartments to be broken off from the container after the
container has been broken apart on the longitudinal center line, so
that individual articles can readily be dispensed from the
container by the user.
A blister element, formed of thin clear acetate, for example, is
provided for each compartment for retaining the respective article
therein. FIG. 6 shows one such blister formed of, for example,
acetate material having a thickness of 0.010 inches and vacuum
formed so as to have a substantially rectangular cavity 40 with a
peripheral rim 42 projecting laterally from the open end of the
cavity.
The dimensions of rim 42 is slightly greater in each direction than
the respective dimensions of the compartment in which it is to be
disposed so that when the blister is pressed in place in a
compartment it will be compressed slightly and will remain therein.
One such blister is shown in dot-dash outline in FIG. 5 by the
reference numeral 44.
Normally, a container will receive articles of a single size only
and all of the blisters placed in the container to retain the
articles in place would, therefore, be of a single size only. The
container shown makes up a package of 10 of the articles and an
entire package can be sold or the package can be broken in two and
a half package containing 5 articles can be sold. If an entire
package is sold, the purchaser can break the package in half and
then each individual compartment of the package can be broken off
singly for dispensing the articles therefrom.
As will be seen in FIG. 7, ribs or knobs or other protuberances 46
could be provided adjacent the bottom wall of the compartments for
engaging the rim of the blister if so desired. The provision of
such protuberances will substantially eliminate any possibility of
the blisters coming out of the compartments accidentally even if
the packages are roughly handled during shipping.
As mentioned, the blisters used with the container all have the
same longitudinal dimension X, as shown in FIGS. 8 and 9, and the
same dimension Y at right angles thereto. To accommodate the
package to articles of different size and/or different shape, the
blisters are differently formed as shown in FIGS. 8 and 9.
The blister shown in FIG. 8 has a generally rectangular cavity 50
formed therein with small pocket regions; 52 in the center of one
side and 54 at the ends of the opposite side. This blister is thus
adapted for holding square articles of a certain size, round
articles of substantially the same diameter as the length of a side
of the square article, triangular articles of a size such that the
apices thereon will enter pockets 52 and 54, and diamond shaped
articles.
The blister shown in FIG. 9 has a cavity 56 adapted for receiving
diamond shaped articles.
It will be evident that the blisters could be formed to
substantially any size and shape and all the possibilities have not
been illustrated herein but only enough have been illustrated to
show that a multiplicity of different sizes and shapes can be
packaged in one and the same container having compartments all of
the same size and shape.
FIG. 7 shows protruberances 46 for engaging over the flange of the
blister element to hold the blister element in the compartment of
the main container part but it will be appreciated that the flange
of the blister element could also be retained in place by forming
groove means about the periphery of the compartment near the bottom
for receiving the flange of the blister element could be heat
sealed or otherwise sealed to the bottom wall of the respective
compartment if so desired.
It will be apparent that modifications could be made in the
structure illustrated and described and that the invention is
determined by the scope of the appended claims.
